Used MAS Equipment For Sale

Mas was founded in 2006 by Helmuth Schulz, a recycling pioneer with more than four decades of experience in plastics machinery manufacturing. Recognizing that the recycling equipment of the era could not meet the quality demands of modern reuse, Schulz developed the patented conical, co-rotating twin screw extrusion concept — widely regarded as one of the most significant innovations in mechanical recycling of recent decades. In 2017 ownership passed to Katharina Schulz, keeping Mas a family-owned business into its second generation, and the company has continued to expand its production site and workforce in Upper Austria ever since.

The heart of the Mas product range is its conical, co-rotating twin screw extruder, available across multiple size classes. The MAS 24 and MAS 55 serve laboratory and mid-range production duties, the MAS 55L is optimized for rPET recycling lines, the MAS 75 targets outputs up to roughly 1,100 kg/h, and the flagship MAS 110 — developed with AI-assisted simulation — delivers up to six metric tons per hour of PET. All models share a large-volume feed opening, segmented barrel construction for selective wear-section replacement, air-cooled discharge, and a modular screw design whose individual elements can be swapped independently. The conical geometry provides exceptionally large back-pressure bearings and high torque exactly where the melt needs it most, enabling low screw speeds, gentle polymer treatment, and energy savings of up to 40 percent compared with conventional parallel twin screw designs.

Mas twin screw extruders serve processors across plastics recycling and upcycling, post-consumer and post-industrial film recycling, PET bottle-to-bottle and food-contact rPET production, polyolefin and engineering-resin compounding, masterbatch production, and direct film extrusion. End markets include flexible and rigid packaging, food-grade film, fiber and nonwoven production, and the broader circular-economy supply chain where recycled-content material must meet virgin-equivalent quality standards.

Buyers seeking used Mas twin screw extruders are drawn by the machines' robust mechanical construction, comparatively low wear rates, and the modular screw-and-barrel architecture that keeps refurbishment costs manageable. The conical design's inherent energy efficiency translates directly into lower operating costs on the secondary market, and the global installed base of more than 200 units means spare parts and process expertise are readily accessible. These factors, combined with strong resale values driven by sustained demand for plastics recycling capacity worldwide, make pre-owned Mas extruders a compelling choice for recyclers and compounders looking to scale up without the lead times of new equipment.
